Exploring pulsational instabilities in the O-type supergiant HD 152249
Subharthi Dasgupta, Abhay Pratap Yadav, Sugyan Parida +1
Variability in O-type supergiants is a well known phenomena although their origin is not fully understood. In very massive, luminous stars, strange mode pulsations have been sugges…

Scalable Bayesian data curation for next-generation radio experiments
S. A. K. Leeney, E. de Lera Acedo, W. J. Handley +42
Next-generation radio telescopes produce data volumes that preclude manual quality assessment, yet data curation remains essential for science. We present a general, fully automati…

On the origin of variability in Cygni variable Ori (HD 37128) using TESS observations and modelling
Subharthi Dasgupta, Sugyan Parida, Abhay Pratap Yadav +2
Ori (HD 37128) is an Cygni variable characterized by irregular and small amplitude variations. From TESS observations, we find the presence of stochastic low-frequency vari…
